One of it's main strengths probably was how easy it is to use (e.g. plenty of the competitors you can't just sign up for a free account and then invite people without an account) while working very well (which many of the WebRTC-based competitors in the "easy and free to use" category struggle(d) with). And then it quickly becomes self-reinforcing: if people get introduced to it they'll use it too unless they have a good reason to seek something else, which gave it a boost once video conferencing suddenly was something many people needed. (by now Microsoft Teams has anecdotally taken over lots of the corporate use, tech-y communities have gotten around to bring their own jitsi and BBB instances up, ...)
Tbh, I still have not ever participated in a Google Meet meeting, so this probably also very much depends on the markets etc.
The result was an accelerated product roll-out; necessity being the mother of invention etc.
Now, I don't know for a fact that other firms were in a similar position but it seems at least as likely as the conspiracy theory version of the story.
Because Google Meet is crap, you can't depend on Google keeping a product long-run, and Zoom already had integrations with tons of other apps and hardware (including Slack).
Because it was already the best and up-coming tele-conference tool before 2020?
>I believe I generally keep tabs on up and coming technology companies and never heard of Zoom until mid March.*
Apparently not that good tabs...
"Eric Yuan, a former Cisco engineer and executive, founded Zoom in 2011, and launched its software in 2013."
"In January 2017, the company raised US$100 million in Series D funding from Sequoia Capital at a US$1 billion valuation making it a "unicorn" company."
"The company first became profitable in 2019, and completed an initial public offering that year."
"On April 18, 2019, the company became a public company via an initial public offering. After pricing at US$36 per share, the share price increased over 72% on the first day of trading.[43][7] The company was valued at US$16 billion by the end of its first day of trading.[7] Prior to the IPO, Dropbox invested $5 million in Zoom."
Other examples are calling a tissue a Kleenex, calling a vacuum a Hoover, calling a cola a Coke, and so on.
Many mainstream people call a video conference a Zoom and it happened to stick.
1) pandemic immediately put people online for jobs/schools, requiring collaboration
2) zoom is easy to use
3) zoom was sketchy with privacy/security and that got a lot of media attention (because it became critical infrastructure for jobs/schools/etc)
That and the conspiratorial tone, probably.
> Hmmm...guess CCP got to keep Zoom alive.
